Watch: Chargers' Addae returns 1st career INT for 90-yard TD

The Chargers are intent on playing spoiler in maybe their last game in San Diego.

Down 20-10 and in need of a game-changing play Sunday against the Kansas City Chiefs, the Chargers got one from safety Jahleel Addae, who picked off Alex Smith and made several Chiefs miss en route to a 90-yard touchdown return.

It was the fourth-year pro's first career interception.
